This invention relates to a damper so con structed that the block neednot be bored for the reception of the damper-wire, and is therefore notliable to be split. The damper is also so constructed that the head maybe readily glued to the block at any desired an gle to the wire, so asto be in proper position above the string.

The invention consists in the various features of improvementhereinafter more fully pointed out.

The head h of the damper is cushioned, asusual, and is provided with a hook or projection, It, having a curvedinner edge, Fig. III, that bears and fits against the cylindrical block1 the curvature of hook it Corresponding to the curvature of the blockg. It will be seen that the head It may be glued to block {1 at anyinciina tion to the wire (I, thus bringing the damper in proper positionover string 8, Fig. II, the rounded edge of the hook h properly engagingat all times the eircum ference of the block.
